Online Image to ICO Converter
Creating Icons from Images
Converting images to ICO format creates icons for websites, applications, and operating systems. The ICO format supports multiple sizes in a single file, allowing the same icon to be used for taskbars (16x16), shortcuts (32x32), and desktop icons (48x48 or 256x256).
Our tool automatically generates all standard icon sizes from your uploaded image. For best results, use a simple, recognizable design with transparent background. Complex photographs generally don't make good icons — simple logos or symbols work best.
